LOCK-PLATE FOR PORTABLE RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 315,606, dated April14:, 1885.

Application filed December 11, 1884. (No model.)

To all whom it may concern:

Be it known that I, HENRY FRANKIE, a citizen of the United States, and aresident of Brooklyn, in the county of Kings and State of New York, haveinvented a certain new and useful Improvement in LoclzPlates forPortable Railways, of which the following is a specification.

My invention is an improvement upon the invention for which a patent wasissued to A. Bass for improvement in portable railways, No. 164,252,June 8, 1875, and is as follows, reference being had to the accompanyingdrawings, in which Figure 1 is a longitudinal view, partly in section,through the ends of two sections of a portable railway, showing thelocking device in side View. of a portable railway, showing the lock inposition. Fig. 3 is a perspective view of my locking device.

Similarletters refer to similar parts th roughout the several views.

This invention relates to portable railways; and it consists in alocking device to prevent longitudinal displacement of the sectionsthereof. To attain this object, I secure to the end ties or cross-piecesa a, connecting the rails A A of each section, the plates F, by rivetingone end of each to a cross-tie, a. The

other end of the plate F is formed into a hoolr,

Fig. 2 is a plan view of sections f. This hook f projects so far beyondthe end of the section to which itissecured that it will hook over theend tie a. of the adjoining section, preventing longitudinaldisplacement. The plate F may also be bent slightly upward, as shown inFig. 1, to facilitate laying curves or differentangles of grading. Eachend tie a generally has two of'the hook-plates F secured to it, thehooks on each end of two adjoining sections engaging with the end tie ofthe other, as shown in Figs. 1 and 2, thus forming a perfect lock.

I am aware that prior to my invention portable railway-sections havebeen made with straight lapping pieces securing against lateral motion.I therefore do not claim such a combination, broadly; but

What I do claim as my invention, and desire to secure by Letters Patent,is-

The combination, in a portable railway, of the rails A A and end ties aa with the lockplates F, having the hooksf, as and for the purposeherein shown and described.

Signed at Brooklyn, in the county of Kings and State of New York, this5th day of December, A. D. 188i.
